Basic Circuits and Ohm's Law

Front

What is an open circuit?

Back

An open circuit is a circuit that is not complete, meaning there is a break in the path for current to flow.

Front

What unit is used to measure voltage?

Back

Volts (V) is the unit used to measure voltage.

Front

What happens to resistance when the length of a wire increases?

Back

The resistance increases.

Front

How do you calculate current in a circuit?

Back

Current (I) can be calculated using Ohm's Law: I = V/R, where V is voltage and R is resistance.

Front

What unit is used to measure resistance?

Back

Ohms (Ω) is the unit used to measure resistance.

Front

What is a closed circuit?

Back

A closed circuit is a complete circuit that allows current to flow.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

Front

What is the formula for calculating voltage?

Back

Voltage (V) can be calculated using the formula: V = I × R, where I is current and R is resistance.

Front

What is the relationship between voltage, current, and resistance?

Back

Voltage is equal to the product of current and resistance (V = I × R).

Front

What is a series circuit?

Back

A series circuit is a circuit in which the components are connected end-to-end, so the current flows through each component one after another.
