Question

С=100мКФ U=90kB q-? С=2640 пф U=120B q-?

Answer 1

Q=C*U => 0,0001Ф* 90000В =

= 9 кулон

Answer 2

To find the charge (q) in each case, you can use the formula:

q = C * U

where: q = charge (in coulombs) C = capacitance (in farads) U = voltage (in volts)

Let's calculate the charges for each case:

1. C = 100mF, U = 90kV

Convert 100mF to farads: 100mF = 100 * 10^(-3) F = 0.1 F Convert 90kV to volts: 90kV = 90 * 10^3 V = 90000 V

q = 0.1 F * 90000 V q = 9000 coulombs

So, the charge (q) in this case is 9000 coulombs.

2. C = 2640pF, U = 120V

Convert 2640pF to farads: 2640pF = 2640 * 10^(-12) F = 2.64 * 10^(-9) F U = 120V

q = 2.64 * 10^(-9) F * 120 V q = 3.168 * 10^(-7) coulombs

So, the charge (q) in this case is approximately 3.168 * 10^(-7) coulombs.
