Question

To calculate the effective resistance of a circuit with resistors in parallel the following equation can be used: Reffactive R R2R R,n a. If the resistance of each resistor is labelled R, to R, write the effective resistance of the circuit in sigma notation b. The voltage applied to the circuit varies with time, t, and the initial voltage variation applied to the circuit is described by the function oi. Find a binomial series approximation of the voltage using the first three terms of the series,f(t) = (1 + t)i ll. Find the voltage approximation at time t 0.8 seconds, giving your answer to two significant figures iii. Find the percentage error for the approximation at t = 0.8seconds, giving your answer to the nearest whole percent. c. The current flowing through a resistor is / If all the resistors have a value of 800 ohms, use your approximated value of voltage at t - 0.8 seconds to calculate the current / produced by the voltage source. Give your answer to two significant figures
