Ohm's Law: Calculators

Calculators
• Current (I)
• Power (P)
• Resistance (R)
• Voltage (E)
• Ohm's Law Pie Chart

Calculate for Current (I)

I = P / E

Power	Voltage		Current

Watts	Volts		Amps

I = Square Root of (P / R)

Power	Resistance		Current

Watts	Ohms		Amps

I = E / R

Voltage	Resistance		Current

Volts	Ohms		Amps

Calculate for Power (P)

P = I ² x R

Current	Resistance		Power

Amps	Ohms		Watts

P = E x I

Voltage	Current		Power

Volts	Amps		Watts

P = E ² / R

Voltage	Resistance		Power

Volts	Ohms		Watts

Calculate for Resistance (R)

R = P / I ²

Power	Current		Resistance

Watts	Amps		Ohms

R = E / I

Voltage	Current		Resistance

Volts	Amps		Ohms

R = E ² / P

Voltage	Power		Resistance

Volts	Watts		Ohms

Calculate for Voltage (E)

E = I x R

Current	Resistance		Voltage

Amps	Ohms		Volts

E = P / I

Power	Current		Voltage

Watts	Amps		Volts

E = Square Root of (P x R)

Power	Resistance		Voltage
