Below are two do circuit schematic diagrams. Please answer the following questions by referencing them by Diagram A (on the left} and Diagram B (on the right). R1 R: 3' % R: Ra a. How many resistors are present in Diagram A? Diagram B? b. Which diagram has resistors arranged in parallel? In series? c. If each resistor is 10.0 (I, calculate the equivalent resistance for Diagram A. cl. If each resistor is 10.0 (I, calculate the equivalent resistance for Diagram B. e. If the battery supplies 9.00 V to the circuit, calculate the total current in Diagram A. f. It the battery supplies 9.00 V to the circuit, calculate the total current in Diagram B
