Total questions: 15
Worksheet time: 8mins
What is voltage defined as?
The rate of flow of charge
The change in potential energy per unit charge
The resistance in a circuit
The power consumed by a device
What does Ohm's Law relate?
Voltage and power
Voltage and current
Power and resistance
Current and resistance
What is the formula for calculating current using Ohm's Law?
I = V*R
I = R + V
I = V/R
I = R/V
What is the unit of resistance?
Ohm
Volt
Ampere
Watt
What happens to total resistance when more paths are added in a parallel circuit?
It increases
It decreases
It remains the same
It becomes infinite
What is electric power defined as?
The voltage across a circuit
The total energy consumed
The rate at which energy is transferred
The current flowing through a circuit
What does a resistor do in a circuit?
Increases voltage
Decreases current
Stores energy
Generates power
In a series circuit, how many paths are there for the electrons?
Multiple
Three
Two
One
What is the relationship between voltage (V), current (I), and resistance (R) in Ohm's Law?
V = I / R
V = I - R
V = I * R
V = I + R
What is the effect of increasing resistance in a circuit?
Increases voltage
Decreases current
Increases current
Decreases power
What is the unit of electric current?
Volt
Ohm
Watt
Ampere
What does a voltmeter measure?
Current
Resistance
Power
Voltage
What is the direction of current flow in relation to electron flow?
Random direction
Perpendicular direction
Opposite direction
Same direction
What is resistivity?
The area of a conductor
The length of a conductor
The voltage across a conductor
A measure of a material's resistance
What is the formula for power in terms of voltage and current?
P = V + I
P = V * I
P = V / I
P = I / V
