Ok so if you have to take the 5 amperes and multuply them by the 22 ohm resistance giving you the answer of 110
5
*
22
=
110 volts
U = RxI so 11x20=220 volts
Resistance calculations are the same no matter what the polarity of applied voltage. R=E/I Resistance (in ohms) = Voltage (in volts) divided by Current (in amperes)
Ohm's law: Voltage is resistance times current. 80 ohms time 0.5 amperes = 40 volts.
The voltage is 3 x 36 or 108 volts.
6 amperes
U = RxI so 11x20=220 volts
Use Ohm's law. V = I * R where V is voltage in volts, I is current in amperes, and R is resistance in ohms.
0.02 amperes
9 amperes.
You don't. If you know how many Amperes in an electrical circuit and also what the total resistance in the circuit is, then EMF (Volts) = current (Amps) x resistance (in Ohms). EMF stands for Electromotive Force, and its unit of measure is the Volt.
Resistance calculations are the same no matter what the polarity of applied voltage. R=E/I Resistance (in ohms) = Voltage (in volts) divided by Current (in amperes)
It looks as if you can use Ohm's Law to calculate this: V=IR (voltage = current x resistance).
Electrical current is measured in amperes.
Ohm's law: Voltage is resistance times current. 80 ohms time 0.5 amperes = 40 volts.
A capacitor can release its stored energy at any rate. The rate is determined by ohm's law. It states that the current in amperes equals the electromotive force (or voltage difference of the capacitor's poles) divided by the resistance between the poles. I=E/R Current=volts/resistance
The voltage is 3 x 36 or 108 volts.
The unit of resistance is the Ohm, and by applying a small voltage to your wire, and measuring the resultant current, you may calculate the resistance.From the formula I = E/R, where R = resistance in Ohms, E is the voltage in volts, and I is the current in amperes.
