Question

Q=24 Джоуля R=2 Ома t, =4 C I=?

Answer 1

Ответ:

Объяснение:

Q=I^2*R*t    I=sqrt(Q/R*t)=sqrt(24/2*4)=1,73 A

Answer 2

To calculate the current (I) in the given circuit, we can use Ohm's Law, which states:

V = I * R

where: V is the voltage (in volts), I is the current (in amperes), R is the resistance (in ohms).

We know that Q (charge) can be calculated using the formula:

Q = V * t

where: Q is the charge (in coulombs), V is the voltage (in volts), t is the time (in seconds).

Given Q = 24 Joules and t = 4 seconds, we can rearrange the formula to solve for V:

V = Q / t V = 24 J / 4 s V = 6 volts

Now, we can use Ohm's Law to find the current (I):

I = V / R I = 6 V / 2 Ω I = 3 amperes

So, the current in the circuit is 3 amperes.
