Ohms Law Problems

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 with the formula: V = I * R.

What is the unit of measurement for current?

Back

The unit of measurement for current is Amperes (A).

Front

What is the unit of measurement for resistance?

Back

The unit of measurement for resistance is Ohms (Ω).

Front

If the voltage is 24 volts and the current is 6 amps, what is the resistance?

Back

4 ohms.

Front

What is the formula to calculate voltage?

Back

V = I * R.

Front

What is the formula to calculate current?

Back

I = V / R.

Front

What is the formula to calculate resistance?

Back

R = V / I.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which the components are connected end-to-end, so that the current flows through each component in turn.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit in which the components are connected across common points or junctions, providing multiple paths for the current to flow.

What happens to the total resistance in a series circuit when more resistors are added?

Back

The total resistance increases when more resistors are added in a series circuit.
