FAQs
Question: What is Ohm's Law? Answer: Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points, expressed as V = IR.
Question: How do I calculate total resistance in a parallel circuit? Answer: The total resistance (R_total) in a parallel circuit can be calculated using the formula 1/R_total = 1/R1 + 1/R2 + 1/R3 + ...
Now is the time to enhance your understanding of "Current, Resistance and Ohms Law - Circuit Analysis Techniques". Dive into our practice MCQs and test your knowledge to excel in your exams!
Q. A capacitor with a capacitance of 10μF is charged to a voltage of 5V. What is the charge stored in the capacitor?
A.
10μC
B.
50μC
C.
5μC
D.
100μC
Solution
The charge stored in a capacitor is given by Q = C * V = 10μF * 5V = 50μC.
Q. What is the total current in a parallel circuit with two branches, where one branch has a resistance of 4Ω and the other has 6Ω, connected to a 12V source?
A.
2A
B.
3A
C.
4A
D.
6A
Solution
First, find the equivalent resistance: 1/R_eq = 1/4 + 1/6 => R_eq = 2.4Ω. Then, I = V / R_eq = 12V / 2.4Ω = 5A.
