Question

A parallel plate condenser has a capacitance $110 \mu F$when immersed in an oil. The dielectric constant of the oil is

• A. 0.45
• B. 0.55
• C. 1.10
• D. 2.20

Answer 1

Answer: (D)

2.20

Answer 2

$K = \frac { C _ { \text {medium } } } { C _ { \text {air } } } = \frac { 110 } { 50 } = 2.20$
