Ohms law provides the formula to determine any of the three components in a circuit voltage=E Resistance=R and Current=I so with any two you can figure out the third:

  • I=E/R
  • E=IxR
  • R=E/I

So to find I use I=E/R so you divide the resistance into the voltage and you have the current(in amps) or power.

Power can be found using the equation: power = (voltage)2 / resistance.
The Equation is PIE where P is power in watts. I is current in amps. E is voltage in volts. P equals I times E. 240 watts is created with 120 volts and 2 amps of current

How to determine amp draw in an electrical circuit?

To determine amp draw in an electrical circuit, you can use Ohm's Law, which states that current (amps) equals voltage divided by resistance. Measure the voltage across the circuit and the resistance of the components in the circuit, then divide the voltage by the resistance to calculate the amp draw.


What 2 Factors Determine How Much Amperage Will Flow?

The two main factors that determine how much amperage will flow in a circuit are the voltage of the source supplying the electricity and the resistance in the circuit. According to Ohm's Law, the amperage (current) in a circuit is equal to the voltage divided by the resistance (I = V/R).


If you have a circuit consisting of a battery and a wire What two factors determine the amount of current in the circuit?

The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).


What is the relationship among voltage circuit and resistance in a circuit?

Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)


Is the increase in voltage causes a greater electric resistance in a circuit?

No, the resistance in a circuit does not change when voltage changes. Resistance is an inherent property of the circuit.


What is the relationship among voltage current and resistance in a circuit?

What factors determine the voltage induced in a wire?

V = I * R or I = ( V / R ) I = current (amps) V = Voltage R = Resistance The current in a circuit depends on the applied voltage and the resistance of the circuit.


What will happen in a circuit if the voltage does not change but the resistance in the circuit increases?

If the resistance increases, while the voltage stays the same, current will decrease. Current = voltage divided by resistance


Should you increase voltage or resistance to increase flow in a circuit?

To increase (current) flow in a circuit you increase voltage (or decrease resistance). Ohm's Law: Current = Voltage divided by resistance
