9.2 Att = -250/6 us, a sinusoidal voltage is known to be zero and going positive. The voltage is next zero 1250/6 us. It is also known that the voltage at t = is 75 V at t 0. = a) What is the frequency of u in hertz? b) What is the expression for v?

Given the range find the per scale value for each range based on the encircled basis (follow the line of the black encircled basis) Range: Per scale val.: 0.1 0.5 2.5 10 50 250 1000
