Front

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

Back

The current will increase.

Front

What is the function of a resistor in an electrical circuit?

Back

The ability to reduce the flow of electrons across an electrical circuit.

Front

What is the mathematical relationship among Voltage, Current, and Resistance?

Back

Ohm's Law

Front

What is the unit of electrical resistance?

Back

Ohm (Ω)

Front

What is the effect of increasing resistance in a circuit with constant voltage?

Back

The current will decrease.

Front

What is the formula for calculating electrical power in a circuit?

Back

Front

What is the term for a closed loop through which an electric current flows?

Back

Circuit

Front

What is the difference between series and parallel circuits?

Back

In series circuits, components are connected end-to-end, while in parallel circuits, components are connected across the same voltage source.

Front

What happens to the total resistance in a series circuit?

Back

The total resistance is the sum of all individual resistances.
