A 22.0 Ω, 11.0 Ω, and 6.00 Ω resistor are

connected in parallel to an emf source. A
current of 6.00 A is in the 11.0 Ω resistor.What is the potential difference across the
source?
Answer in units of V

All resistors have the same potential difference since they are connected in parallel. It equals the potential difference of the source.

Use the data for the 11 ohm resistor.
V = I*R = 66 Volts

To find the potential difference across the source, we can use Ohm's Law, which states that V = IR, where V is the potential difference, I is the current, and R is the resistance.

In this case, the current passing through the 11.0 Ω resistor is given as 6.00 A.

Since the resistors are connected in parallel, the potential difference across each resistor is the same as the potential difference across the source.

Therefore, the potential difference across the source is equal to the potential difference across the 11.0 Ω resistor.

Using Ohm's Law, we can find the potential difference across the 11.0 Ω resistor (and across the source) by multiplying the current (6.00 A) by the resistance (11.0 Ω):

V = (6.00 A) * (11.0 Ω)
V = 66.0 V

So, the potential difference across the source is 66.0 V.
