Electric Current and Ohm's Law

Front

In order for electrical current to flow through a wire, the wire must be connected in a ____________ that includes a source of electrical current.

Back

Complete loop

Front

What unit is used to measure current?

Back

Amps

Front

What is a closed path for electrons to flow through?

Back

Circuit

Front

What would happen if in a circuit, the resistance increases but the voltage stays the same?

Back

The current would decrease.

Front

What unit is used to measure voltage?

Back

Volts

Front

What is the relationship between voltage, current, and resistance in a circuit?

Back

Ohm's Law: V = I × R (Voltage = Current × Resistance)

Front

What is resistance in an electrical circuit?

Back

Resistance is the opposition to the flow of electric current, measured in Ohms.

Front

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

Back

The current increases.

Front

What is the formula to calculate electrical power in a circuit?

Back

Power (P) = Voltage (V) × Current (I), measured in Watts.

Front

What is an open circuit?

Back

An open circuit is a circuit that is not complete, preventing current from flowing.
