The voltage will remain constant in the circuit but will be divided among more loads, thus giving each load less voltage.

If the resistance in the circuit is increased what will happen to the current and voltage?

* resistance increases voltage. Adding more resistance to a circuit will alter the circuit pathway(s) and that change will force a change in voltage, current or both. Adding resistance will affect circuit voltage and current differently depending on whether that resistance is added in series or parallel. (In the question asked, it was not specified.) For a series circuit with one or more resistors, adding resistance in series will reduce total current and will reduce the voltage drop across each existing resistor. (Less current through a resistor means less voltage drop across it.) Total voltage in the circuit will remain the same. (The rule being that the total applied voltage is said to be dropped or felt across the circuit as a whole.) And the sum of the voltage drops in a series circuit is equal to the applied voltage, of course. If resistance is added in parallel to a circuit with one existing circuit resistor, total current in the circuit will increase, and the voltage across the added resistor will be the same as it for the one existing resistor and will be equal to the applied voltage. (The rule being that if only one resistor is in a circuit, hooking another resistor in parallel will have no effect on the voltage drop across or current flow through that single original resistor.) Hooking another resistor across one resistor in a series circuit that has two or more existing resistors will result in an increase in total current in the circuit, an increase in the voltage drop across the other resistors in the circuit, and a decrease in the voltage drop across the resistor across which the newly added resistor has been connected. The newly added resistor will, of course, have the same voltage drop as the resistor across which it is connected.


What the advantages of series circuits?

While many of the terminal parts of a circuit may be a series element, in most circuits there will be both series and parallel components. Neither is superior - they both have their appropriate applications.


What happens if you add more batteries to a circuit?

Depends on how you add them. Added in series, the voltage will increase, maybe to the point of damaging the LED. If the LED survives, it will shine brighter. Added in parallell, the LED will shine the same, and will be able to shine longer before draining the batteries.


If three 6 volt batteries are connected in series the overall voltage in circuit is?

Regardless of the number and value of the resistors, total voltage drop in a series circuit will equal the voltage rise, or the applied voltage. Apply 6 volts to three series resistors and the sum of the voltage drops will be 6 volts. No mystery here. Think it through and it will lock in. To get you ready for more "advanced" analysis, Kirchhoff said the algebraic sum of the voltages in any closed loop is zero. Going all the way around a series circuit, we'd encounter the battery, and all the series resistors. The battery is a voltage rise, and the resistors are voltage drops. The polarity of a voltage rise is opposite that of a voltage drop. This means that when they are added algebraically, if they are equal, they will sum to zero. Work this with a battery connected across a single resistor to get a handle on it. You'll need the ideas to manage calculations in loops of parallel circuits. Remember that in any closed loop, the algebraic sum of the voltages is zero.


What will be the breakdown voltage of ciruit if 3 zener diode are connected in series having breakdown voltage of 8 volt each?

A: Any zener connected in series will have each voltage added to the load. Therefore each will add 8 volts to the sum of 24 volts. there will be available at each junction as 8v 16v and finally 24volts

What happens to the voltage across the voltage source as more light bulbs are added in a series circuit?

Nothing.


What happens to the voltage if batteries if they are setup in a parallel and a series circuit?

Assuming all of the individual batteries are the same voltage, if arranged in a parallel circuit the voltage is the same as any one battery. If arranged in a series circuit the voltage will be the sum (the total) of all of the batteries added together.


What happens when one bulb is added to a series circuit?

The resistance is increased, the voltage across each bulb is decreased and the current through the circuit is reduced.


When two cells with the same voltage are connected in a series circuit what happens to the voltage?

There is addition of voltage. Dry cells have 1.5 volts irrespective of there size. if the cells are added as same polarity in series it will add if are parallel then voltage remains same


What happens to the voltage as more bulbs are added in series?

The total voltage should not change in this case.


What happens to the lamp in a series connecting if more loads are added?

The lamps each get more dim with each load added, because in a series circuit, the amount of voltage per load is determined by the total voltage divided by the amount of loads. If one lamp burns out, the rest stop working because with that one burnt lamp, the circuit is broken


What is total voltage in a series circuits?

In a series circuit the total voltage is the sum of the voltage drops across all the component in series. When the voltage drops across each the individual components are added up, they will equal the supply (or applied) voltage.


In a series circuit each device that is added to the circuit decreases the what?

Depends on the device. If it is a resistor and you have a fixed voltage then the circuit will obey Ohms law. Voltage = Current x Resistance. So if R increases by adding more resistors in series and the voltage is constant, the current will decrease.


What happens to the other lamps in a series connection if more loads are added?

The lamps each get more dim with each load added, because in a series circuit, the amount of voltage per load is determined by the total voltage divided by the amount of loads. If one lamp burns out, the rest stop working because with that one burnt lamp, the circuit is broken

Ohm's Law answers your question. Voltage = Current x Resistance. In a series circuit you are in effect adding resistance. If the Voltage remains constant then the answer is obvious looking at the equation above.
