Ohm's Law Calculations

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. It is expressed as V = I * R.

What is the formula for calculating current using Ohm's Law?

Back

I = V / R

What is the formula for calculating voltage using Ohm's Law?

Back

V = I * R

What is the formula for calculating resistance using Ohm's Law?

Back

R = V / I

How is power calculated in a circuit?

Back

Power (P) is calculated using the formula P = V * I, where P is power in watts, V is voltage in volts, and I is current in amperes.

Front

What happens to current if voltage is increased while resistance remains constant?

Back

If voltage is increased while resistance remains constant, the current will increase.

Front

What happens to current if resistance is increased while voltage remains constant?

Back

If resistance is increased while voltage remains constant, the current will decrease.
