Five resistors are wired in the shown configuration. R1 through R5 are 25ohms, 75ohms, 15ohms, 50ohms, and 35ohms respectively. A multimeter is used to check the voltage drop of R3 and is found to be 1V. Find the following: a) The total resistance of the circuit b) The current through R1 c) The battery voltage All work/explanations must be shown to receive credit. DO NOT leave out steps. A picture must be submitted at the end to receive credit.

Seven resistors are wired in the shown configuration. All resistors are identical 60ohm resistors. The ammeter in the picture reads 0.5mA. Find the following a) The total resistance of the circuit b) The voltage drop of R6 c) The battery voltage All work/explanations must be shown to receive credit. DO NOT leave out steps. A picture must be submitted at the end to receive credit.
