I need some help with the process for Part A-C please

Problem 2: A circuit with a resistance R = 131 $ is connected to a battery with potential difference across the terminals of AV = 5.5 V. ans Part (a) Input an expression for the current passing through the circuit, I. Expression : Select from the variables below to write your expression. Note that all variables may not be required. a, B, AV, 0, a, d, g, h, j, k, m, P, R, S, t Part (b) What is the current in milliamps, mA? Numeric : A numeric value is expected and not an expression. I = Part (c) If the resistance of the circuit was increased by a factor of ten, Rnew = 10R, what is the new current in milliamps, mA? Numeric : A numeric value is expected and not an expression. Inew =
