Question 1
What is the unit of measurement for electrical resistance?
, A) Volt
B) Ampere
C) Ohm
D) Watt
Answer: C) Ohm
Rationale: The ohm (Ω) is the SI unit of electrical resistance, named after Georg Simon Ohm.
Resistance is the opposition to the flow of electric current.
---
Question 2
According to Ohm's Law, what is the formula for calculating voltage?
A) V = I × R
B) V = I / R
C) V = R / I
D) V = I² × R
Answer: A) V = I × R
Rationale: Ohm's Law states that voltage (V) equals current (I) times resistance (R): V = I × R.
This is the fundamental relationship in electrical circuit analysis.
