Answer: 40V

Explanation: A P E X

Answer 2

The voltage drop across the 20 Ohm resistor is 40V.

To determine the answer, we need to know about the current flowing through the resistor.

What is the total resistance of the circuit?

As the three resistors are connected in series, so the resultant resistance is

   10 Ohmv+ 20 Ohm + 30 Ohm = 60 Ohm

What is the current flowing through the resistors?

• As these resistors are connected in series, so the amount of current flowing through each resistor is equal.
• According to Ohm's law, current = voltage/resistance

                           Current= 120/60 = 2 A

What is the voltage across the 20 Ohm resistor?

According to Ohm's law, voltage across the 20 Ohm resistor

                      = current×resistance

                      = 2×20

                      = 40volt

Thus, we can conclude that the voltage across the 20 Ohm resistor is 40V.
