An unknown resistor is connected between the terminals of a 3.00 V battery. Energy is dissipated in the resistor at the rate of 0.745 W. The same resistor is then connected between the terminals of a 1.50 V battery. At what rate is energy now dissipated?

P = 0.186W

Explanation: Energy dissipated in this question is tantamount to power.

P = IV

But V = IR

Since the resistor is the same, we can use it in the second solution in the second connection to get power.

Please find the attached file for the solution

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

i had this question and the answer was 3.15 miles.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles
