What is an ammeter used to measure?

Back

Current

Front

What characterizes a series circuit?

Back

The same current flows through all components.

Front

What is the formula to calculate voltage drop across a resistor?

Back

Voltage drop (V) = Current (I) x Resistance (R)

Front

How do you calculate total resistance in a series circuit?

Back

Total Resistance (R_total) = R1 + R2 + R3 + ...

Front

What is Ohm's Law?

Back

V = I x R (Voltage = Current x Resistance)

Front

What is the unit of electrical resistance?

Back

Ohm (Ω)

Front

What is the unit of electric current?

Back

Ampere (A)

Front

What is the unit of voltage?

Back

Volt (V)

Front

How do you calculate current through a resistor in a series circuit?

Back

Current (I) = Voltage (V) / Total Resistance (R_total)

Front

What happens to the total resistance when resistors are added in series?

Back

Total resistance increases.
