What is the terminal voltage of a large 1.54-v carbon-zinc dry cell used in a physics lab to suppy 2.00 a to a circuit, if the cell's internal resistance is 0.100-12 (b) (6 points) how much electrical power goes to its load?

terminal voltage = 1.34 V

power = 2.68 W

Explanation:

given data

voltage E = 1.54 V

current  = 2A

internal resistance = 0.100 ohm

to find out

terminal voltage and electrical power

solution

we know terminal voltage formula is

terminal voltage = E - current × resistance

terminal voltage = 1.54 - ( 2 × 100 )

terminal voltage = 1.34 V

and

power is calculated by ohm law

Power = V × current

power = 1.34 × 2

power = 2.68 W

0.19 m/s and 0.45 m/s
