Answer 2

Ответ: 0,125В

Объяснение:

Дано:

I=4А

А=10Дж

t=20c

--------------

U-?

А=UIt

U=A/(It)=10/(4*20)=0,125В

Answer 3

Calculating Voltage from Current and Work Done

To calculate the voltage when the current is 4 A and the work done is 10 J with a time of 20 s, we can use the formula:

Voltage (V) = Work Done (W) / Charge (Q)

Where: - Work Done (W) = 10 J - Charge (Q) = Current (I) * Time (t)

First, we calculate the charge using the given current and time: - Charge (Q) = Current (I) * Time (t) = 4 A * 20 s = 80 C

Now, we can use the calculated charge to find the voltage: - Voltage (V) = Work Done (W) / Charge (Q) = 10 J / 80 C = 0.125 V

So, the voltage is 0.125 V.
