Ohm's Law

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) 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 can be expressed as V = I × R.

Front

What is the formula to calculate Voltage?

Back

The formula to calculate Voltage (V) is V = I × R, where I is the current in Amps and R is the resistance in Ohms.

Front

What is the unit of Current?

Back

The unit of Current is Amps (A).

Front

What is the unit of Voltage?

Back

The unit of Voltage is Volts (V).

Front

What is the unit of Resistance?

Back

The unit of Resistance is Ohms (Ω).

Front

If the resistance is 6 Ohms and the current is 8 Amps, what is the voltage?

Back

The voltage is 48 Volts (V = I × R = 8 A × 6 Ω).

Front

If the voltage is 24 Volts and the resistance is 8 Ohms, how do you calculate the current?

Back

The current can be calculated using the formula I = V / R. So, I = 24 V / 8 Ω = 3 Amps.

Front

What happens to current if voltage increases while resistance remains constant?

Back

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

Front

What is Resistance in electrical terms?

Back

Resistance is the ability to reduce the flow of electrons in a circuit.

Front

What is the relationship between Voltage, Current, and Resistance?

Back

The relationship is defined by Ohm's Law: V = I × R.
