Question

Find the capacitance when charge is 20 C has a voltage of 1.2V.

(a) 32.67

(b) 16.67

(c) 6.67

(d) 12.33

The question was posed to me during an online interview.

Origin of the question is Resistances and Capacitances in portion Electrostatic Boundary Value Problem of Electromagnetic Theory

Answer 1

Correct option is (b) 16.67

For explanation I would say: Capacitance is related to Q and V as C = Q/V. Put C = 20C and V = 1.2V, we get Q = 20/1.2 = 16.67 farad.
