What happens to total resistance when resistors are connected in parallel?
Answer: It decreases below the smallest resistor
In a parallel circuit, total resistance is always less than the smallest individual resistor.
Which component stores energy in an electric field?
Answer: Capacitor
A capacitor stores energy in the electric field between its plates.
What is the unit of electrical capacitance?
Answer: Farad
The farad (F) is the SI unit of capacitance, named after Michael Faraday.
In a DC circuit, if voltage doubles while resistance stays the same, what happens to current?
Answer: Current doubles
By Ohm's Law (I = V/R), doubling voltage with constant resistance doubles the current.
What does a diode allow in a circuit?
Answer: Current to flow in one direction only
A diode is a one-way valve for current, allowing flow in only one direction (forward bias).
What is the relationship between frequency and period of a wave?
Answer: Frequency equals 1 divided by period
Frequency (f) and period (T) are reciprocals: f = 1/T.
Which type of circuit has only one path for current to flow?
Answer: Series circuit
In a series circuit, all components share a single current path, so the same current flows through each.
