Question
Three resistors with values of 7.0 ,12 , and 15 are connected in series in acircuit with a 7.5 V battery. What is the total equivalent resistance? What is the current in each resistor? A At what rate is energy delivered to the 15 resistor? W Three resistors with values of 7.0 ,12 , and 15 are connected in series in acircuit with a 7.5 V battery.

W Three resistors with values of 7.0 ,12 , and 15 are connected in series in acircuit with a 7.5 V battery. What is the total equivalent resistance? What is the current in each resistor? A At what rate is energy delivered to the 15 resistor? WExplanation / Answer
the total resistance: R=7+12+15=34 => the current in each resistor : I=U/R=7,5/3,4 =2,206 A the rate energy delivered to the 15 resistor (power of15 resistor) P=I^2.R3= 2,206^2.15= 73,997 W
