What happens to the brightness of a bulb when more bulbs are added in parallel?
The brightness of the bulbs decreases.
The brightness of the bulbs increases.
The brightness of the bulbs remains the same.
The brightness of the bulbs fluctuates.
What is the purpose of a switch in an electric circuit?
To regulate the voltage
To generate electricity
To increase the resistance in the circuit
To open or close the circuit
What is the formula to calculate electrical power?
Power (P) = V x I
Power (P) = V - I
Power (P) = V + I
Power (P) = V / I
What is the relationship between voltage, current, and resistance in a circuit?
V = I ^ R
V = I / R
V = I * R
V = I + R
