- Figure 1 shows a circuit which connects four resistors and three batteries. Calculate the currents I1, I2, I3 and I4 by applying a Kirchhoff’s rules. Neglect the internal resistance in each battery.Three resistors having resistances of 4.0 Ω, 6.0 Ω, and 10.0 Ω are now connected in series. If the combination is connected to an ideal 12-V. What is the total resistance of the circuit? What is the current through each resistor? What is the voltage drop across each resistor? What is the power dissipated by the 6.0 Ω resistor? Clearly state the formulae you’re using and what your letters/symbols mean.Solve systematically and completely. Highlight final answers. A power supply has an output of 12 volts. A group of three resistors in series is connected to its terminals. Two of the resistors have resistances of 3Ω and 1Ω while the third is unknown. A voltmeter connected across the unknown resistance reads 6 volts. Determine a) The unknown resistance. b)The total current through the resistors. c)The voltage across the 3Ω resistor. d) The voltage across the 1Ω resistor.
