I = E / R

If the voltage across the resistor is 90 volts, and the resistance of the resistor

is 9 ohms, then the current through the resistor is

90/9 = 10 Amperes.

Don't try this at home!

The power dissipated by the resistor is E2/R = (90)2/9 = 900 watts. That's comparable to the power (heat) dissipated by a small toaster. A common composition resistor will get hot and possibly explode if it's asked to dissipate that kind of power.

The magnitude of the current will, of course, be somewhat lower because of the additional resistance.

What is the current across a 10k resistor and 20 volts?

First of all, current goes straight through the resistor, not across it.If the potential difference between the ends of the resistor is 20 volts,and its resistance is 10,000 ohms, then the current through it isI = E/R = 20/10,000 = 0.002 ampere = 2 milliamperes


What is the current running through resistor three of 30 ohms if the volts are 90 volts?

Ohm's Law: Current = Voltage divided by resistance90 volts divided by 30 ohms = 3 amperesBe careful if you try this, it is also 270 watts, so the resistor will get very, very hot. Also, since everything has a temperature coefficient, do not expect the resistance when hot to be the same as the resistance when cold.


What is the voltage drop across a 12 ohm resistor with a source of 24 volts?

If there's nothing else between the ends of the resistor and the power supply, then the voltage across the resistor is 24 volts, and the current through it is 2 amperes.

The value of the resistor has 5 volts across it and has 20mA flowing through it?

A 120 ohm resistor a 60 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source What is the current running through the 120 ohm resister?

If they're in parallel, then the resistors have no effect on each other. The current through each one is the same as it would be if the others were not there at all. The current through the 120Ω resistor is 120 volts/120Ω = 1 Ampere. The 60Ω and the 40Ω are red herring resistors.

What is the power dissipated by a resistor that has 5 amps flowing through it with 120 volts applied?

The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).

What is the total dissipative power for a 600 Ohm resistor with 75mA flowing?

Ohm's Law: Volts = Amps * Ohms That means that you have 45 volts across the resistor. Power = Volts * Amps That means that you 3.375 Watts going through the resistor.Alternative AnswerMultiply the square of the current by the resistance.
