Question

T-20 секунд R-250 ом y-2 ампер найти-Q A P

Answer 1

Якщо ти написав 2 ампера то це І;
А=Q;
A=I^2*R*t;
A=4*250*20=20000Дж;
Q=20000Дж як і робота;
Р=A/t;
P=20000/20=1000Вт;

Answer 2

To find Q, A, and P, we need to use the formulas for electric charge (Q), electric current (I or A), and power (P).

1. Electric charge (Q) is measured in coulombs (C) and is calculated using the formula: Q = I * t where I is the electric current in amperes (A) and t is the time in seconds (s).

2. Electric current (I or A) is given as 2 amperes (y = 2 A).

3. Power (P) is measured in watts (W) and is calculated using the formula: P = I^2 * R where I is the electric current in amperes (A) and R is the resistance in ohms (Ω).

4. Resistance (R) is given as 250 ohms (R = 250 Ω).

Now, let's calculate Q, A, and P:

1. Electric charge (Q): Q = 2 A * 20 s Q = 40 C

2. Power (P): P = (2 A)^2 * 250 Ω P = 4 A^2 * 250 Ω P = 1000 W

So, the results are:

• Electric charge (Q) = 40 coulombs (C)
• Power (P) = 1000 watts (W)
