Lesson Worksheet: Analyzing Combination Circuits Physics • 9th Grade
In this worksheet, we will practice determining the currents through and voltages across parts of circuits that contain resistors both in series and parallel.
Q5:
The circuits (a) and (b) appear very similar but are slightly different from each other. What is the difference in the total current between the circuit shown in diagram (a) and the circuit shown in diagram (b)? Give your answer to one decimal place.
Q10:
The diagram shows a circuit containing two cells.
What is the current at the negative terminal of the 15-volt battery? Give your answer to one decimal place.
What is the current at the negative terminal of the 12-volt battery? Give your answer to one decimal place.
What is the current through the 3.8 Ω resistor? Give your answer to one decimal place.
