You have a 4 ohm resistor and a 6 ohm resistor connected in series with a 12.0 volt battery. What is the voltage drop across the 6 ohm resistor (in volts)?
here given
4 resistor and a 6 resistor connected in series
with a 12.0 volt battery = V
4 and 6 are connected in series
Req = R1 + R2
= 4 + 6
Req = 10
using Ohm's Law V = i Req
i = V / Req
= 12 / 10
i = 1.2 A
the voltage drop across the 6 resistor is say V ' = ?
V ' = i R6 ohm
= 1.2 x 6
V ' = 7.2 volts
the voltage drop across the 6 resistor is say V ' = 7.2 volts
