Ch. 6 Electricity Formative #2

Front

What is the formula to calculate current (I) in a circuit?

Back

I = V/R, where I is current in Amps, V is voltage in Volts, and R is resistance in Ohms.

Front

What is voltage?

Back

Voltage is the electric potential difference between two points in a circuit, often referred to as the 'push' that drives electric charges.

Front

What is the unit of measurement for resistance?

Back

Ohm (Ω) is the unit of measurement for resistance.

Front

What does a closed circuit mean?

Back

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

Front

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

Back

Ohm's Law.

Front

What is the symbol for a battery in a circuit diagram?

Back

A battery is represented by a series of long and short parallel lines.

Front

What is the unit of current?

Back

Ampere (A) is the unit of measurement for electric current.

Front

How do you calculate the total current in a circuit with multiple resistors in series?

Back

The total current is the same through all components in a series circuit.

Front

What is the effect of increasing resistance on current in a circuit?

Back

Increasing resistance decreases the current, according to Ohm's Law.

Front

What is the purpose of a fuse in a circuit?

Back

A fuse protects the circuit by breaking the connection if the current exceeds a certain level.
