Series circuit connected to a d.c power supply of 12volts
R1 300ohms
R2 480ohms
R3 220ohms
is the total resistance 1000ohms?
is the total circuit supply current, 12/1000=0.012A?
the potential difference in volts across EACH resistor?
R1 300*0.012=3.6v?
R2 480*0.012=5.76v?
R3 220*0.012=2.64v?
3.6+5.76+2.64=12v?
Parallel circuit connected to a d.c power supply of 12volts
how do i calculate the total circuit resistance?
is it 300+480+220=1000ohms?
how do i calculate the total circuit supply current?
is this how to calculate the current through each resistor?
12v/300=0.04A
12v/480=0.025A
12v/220=0.054A
total= 0.119A?
