Measuring Current, Voltage, and Resistance

How do you calculate voltage?

• Current X Resistance

• Resistance ÷ Current

• Current ÷ Resistance

• Measure it with a ruler

The rate at which the electric charges move. It is measured in amperes (A).

• Voltage

• Current

• Resistance

Is the force (change in electrical potential energy) that causes electric charges to move. It is measured in volts (V).

• Current

• Voltage

• Watts

The amount of opposition to electrical current.

• Power

• Current

• Resistance

The unit for measuring voltage (V)

• Ampere

• Ohm

• Volt

The unit for measuring current.

• Ampere

• Ohm

• Watts

The unit for measuring electrical resistance.

• Watts

• Ohm

• Volt

Says that the voltage of any given circuit is equal to the current flowing through it and the resistance in the circuit. V=IR

• Magnetic Field

• Circuit

• Ohm's Law

An electric current that flows in one direction steadily.

• Direct Current

• Alternating Current

• Magnetism
