Question

In an integrated circuit, the current density in a 2.2-μm-thick x 80-μαη-wide gold film is 7.5 105 A/m Part A How much charge flows through the film in 15 min? Express your answer to two significant figures and include the appropriate units QValue Units Submit Request Answer

Answer 1

Here, for the current

Current = current density * Area

Current = 7.5 *10^5 * (2.2 *10^-6 * 80 *10^-6)

for the charge flow in 15 mins

charge flow = current * time

charge flow = 7.5 *10^5 * (2.2 *10^-6 * 80 *10^-6) * 15 * 60

charge flow = 0.1188 C

the charge flow through the film is 0.1188 C
