Ohm''s Law - Engineering

Q1:

A resistance of 3.3 M is connected across a 500 V source. The resulting current is approximately

A 15.1 µA

B 151 µA

C 66 mA

D 660 mA

ANS:B - 151 µA

Given: 3.3 Mega ohms= 3,300,000, and 500 volts.

According to ohm's law, I = V/R.

Therefore: I = 500/3,300000.

The answer is B. 151 microampere.
