Current in resistor formula
WebIt is possible to replace a series of a resistor with an equivalent resistor. Also, the equivalent resistance of the number of resistors in a series is the sum of the individual resistance values. Besides, the unit of resistance is … WebAs Kirchhoff’s junction rule states that : I1 = I2 + I3. The supply current flowing through resistor R1 is given as : 1.0 + 0.5 = 1.5 Amps. Thus I1 = IT = 1.5 Amps, I2 = 1.0 Amps and I3 = 0.5 Amps and from that information …
