Question

Дано r1=r2=r3=r4=r5=r6=3 ом R-?

Answer 1

Объяснение:

R = n * r    

n - количество сопротивлений, r - сопротивление одного из них

R = 6 * 3 = 18 Ом

Answer 2

To determine the total resistance (R) in a circuit where all resistors have the same value (r1 = r2 = r3 = r4 = r5 = r6 = 3 ohms), we need to consider the circuit's configuration.

If the resistors are connected in series, the total resistance (R) can be calculated by summing up the individual resistances:

R = r1 + r2 + r3 + r4 + r5 + r6 = 3 + 3 + 3 + 3 + 3 + 3 = 18 ohms.

If the resistors are connected in parallel, the total resistance (R) can be calculated using the formula:

1/R = 1/r1 + 1/r2 + 1/r3 + 1/r4 + 1/r5 + 1/r6.

In this case, since all resistors have the same value, we can simplify the equation:

1/R = 1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3 = 6/3 = 2/1.

To find R, we take the reciprocal of both sides:

R = 1/(2/1) = 1 * (1/2) = 1/2 = 0.5 ohms.

So, if the resistors are connected in parallel, the total resistance (R) would be 0.5 ohms.
