Question

Дано:R1=4Ом,R2=15Ом,R3=10 Ом,I=2A, Найти: P1=?

Answer 1

Р1= U*I
U=I*R
U=U1+U2+U3
R =R1+R2+R3
R =4+15+10=29 OM
U1=I*R1=2A*4 OM =8B
U2=I*R2= 2A*15OM =30B
U3=I*R3= 2A*10OM =20B
U=U1+U2+U3
U=8+30+20=58B
P1=58*2=116

Answer 2

Calculation of P1

To calculate P1, we need to use the formula P = I^2 * R, where P is the power, I is the current, and R is the resistance.

Given: - R1 = 4 Ω - R2 = 15 Ω - R3 = 10 Ω - I = 2 A

To find P1, we need to calculate the power across R1.

Using the formula P = I^2 * R, we can substitute the values:

P1 = I^2 * R1 P1 = (2 A)^2 * 4 Ω P1 = 4 A^2 * 4 Ω P1 = 16 A^2 * Ω

Therefore, P1 is 16 A^2 * Ω.

Please note that the given information does not provide the exact value of P1. The calculation is based on the given values and the formula for power.
