DC circuits 1. State Kirchhoff's laws. Use the current {node} law to find I3 in the circuit below. 3. Use Kirchhoff's laws to find the currents flowing through each ofthe resistors in the circuit below and hence calculate the total resistance of this circuit (L0 1.1, L0 1.2, L0 1.3} 4. Use your results from the previous question to calculate the heat generation rate in each ofthe resistors in the circuit above (L0 1.2, L0 1.3} 7. A cell with emf 1.50V is connected in series with a 10.0 (1 resistor and an ammeter that reads 0.144A. What is the internal resistance of the cell? (L0 1.2, L0 1.3}
