If you are looking for the resistance of each resistor in either a series circuit or a parallel circuit you must measure the current I and the voltage V for each resistor. Then calculate its resistance using Ohms Law R = V / I where I = current (Amps), V = voltage (Volts) and R= resistance (Ohms).

How do i find the current?

Current= Volage/Resistance


What will the power be when the resistance is converted from parallel to series connection?

It depends upon the resistance values. Series resistance is the summation of all of the resistances, but to calculate the parallel is more complicated. Once the total resistance of each configuration is known, find the total current for each then multiply the current by the source voltage and this will provide the power.


How do you find total resistance with only voltage?

You can't. You need to find the information about current -- a homework question normally gives you a hint.


What is describe as the total opposition to current flow in a circuit?

Total resistance.


When an ammeter is connected to measure current circuit current will decrease sightly because R total decreases after the meter is inserted?

Current will be decreased because of the resistance of the ammeter added to the circuit's resistance. In other words total resistance increases.


How do you find the current if you have the resistance but not the voltage?

The current will be zero if there is no voltage.


What does the size of the current depend on?

A: The EMF and total resistance


What is the total opposition to a current flow in an AC circuit with both resistance and reactance?

Resistance


What is the mathematical equation to find electric current?

Ohm's law is the basic answer. Voltage = Current * Resistance is ohms law. In order to find current divide voltage by Resistance V/R=I where I is current.


How do you find the value of resistance?

By Ohm's Law, resistance is voltage divided by current.


You are just asking that let us assume you have connected 2 or 3 resistors in a circuit and the current flowing through the circuit and from all the resistors will be same but how?

If the resistors are connected in series, the total resistance will be the sum of the resistances of each resistor, and the current flow will be the same thru all of them. if the resistors are connected in parallel, then the current thru each resistor would depend on the resistance of that resistor, the total resistance would be the inverse of the sum of the inverses of the resistance of each resistor. Total current would depend on the voltage and the total resistance
