Take your circuit voltage and the power of the appliances and divide.E is voltage I is amperage and P is power or wattage. P=ExI Example. 3500 watt heater draws ? Amps on 220Volts I=P/E I= 3500w/220v I= 15.9Amps
INCREASES
"Volts" is electrical pressure applied to a circuit; whereas, "ohms" is electrical resistance to that pressure. One cannot determine ohms from voltage without knowing either the current (in "amps") or power (in "watts"). A normal 120V household circuit can handle a maximum of 20 amps, so using ohm's law of resistance = voltage / current, the minimum resistance required in a 120V household circuit would be 6 ohms. Any less than 6 ohms will cause the circuit breaker to trip.
30 ohms
28 + 56 = 84 ohms
Ohm's law: Volts = Amps * Ohms, or Amps = Volts / Ohms 12 volts / 0.5 ohms = 24 amps
The formula you are looking for is I = sq root of W/R.
ohms=amps/volts Amps= volts/ohms Volts = Amps*Ohms
use ohms law which in this case is volts divided by resistance in circuit
Resistance of the circuit = (voltage across the circuit) divided by (current through the circuit)
To calculate amps in a circuit, use the formula: Amps Volts / Ohms. This formula helps determine the current flowing through a circuit based on the voltage and resistance present.
The resistance of the circuit is measured in ohms.
The formula you are looking for is Ohms = Volts/Amps. R = E/I.
I=e/r
The resistance of the circuit is measured in units of ohms.
Here is the formula you use. I = E/R. I = amperage, E = volts, R = resistance in ohms.
INCREASES
Assuming DC and resistive loads, resistance equals voltage across the load, divided by the current through it. In this case 120/10 or 12 ohms.
