That's Ohm's law. Volts = Current (or Amps) * Resistance.

Potential difference (V)
Voltage or potential difference.
its voltage
The relationship is expressed by Ohm's Law: V=IR (voltage = current times resistance).
Depends on the voltage. R equals V2/P . Or the current: R equals P/I2 .
No. Ohm's law relates voltage, current and resistance: V=IR. ("I" is the symbol for current.)
P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.
Using Ohm's law, we can find the current (I) in a circuit where 3 ohms is the resistance (R) and 12 volts is the appllied voltage (V). [(E) means energy]I = V / R = 12 / 3 = 4 amps.Visit this link http://www.csgnetwork.com/ohmslaw2.html for making Ohm's Law calculations.
Ohm's Law: Voltage equals Resistance times Current Given any two, you can figure out the other using simple algebra.
The power dissipated across a resistor, or any device for that matter, is watts, or voltage times current. If you don't know one of voltage or current, you can calculate it from Ohm's law: voltage equals resistance times current. So; if you know voltage and current, power is voltage times current; if you know voltage and resistance, watts is voltage squared divided by resistance; and if you know current and resistance, watts is current squared times resistance.
Ohm's law: voltage is current times resistance. Restating this; current is voltage divided by resistance, so increasing resistance would decrease current.
Ohms law states that E=I * R, or voltage equals current times resistance. Therefore current equals voltage divided by resistance. 120v divided by 16 ohms equals 7.5 amps.
It usually represents current in amps as in the equation V=IR (volts equals current times resistance)
Ohm's law: voltage is current times resistance 0.03 amperes times 1000 ohms = 30 volts.
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
Electric power is not defined as current divided by voltage. Electric power (Watts) is equal to amps times voltage
It depends on the current going through it. Ohm's law: Voltage equals current times resistance.
Ohm's Law: Voltage is equal to current times resistance 0.002 amperes times 10,000 ohms equals 20 volts.
