Answer 2

The total resistance in electrical circuit depends on the type of connection between the electrical resistances, wether the connection is series or parallel.

If the connection is in parallel,then the formula to calculate the equivalent resistance will be;

1/R= 1/r1 + 1/r2 + 1/r3

1/R = 1/20 + 1/10 + 1/2 [According to the data mentioned in the question]

1/R= (1+2+10)/20

1/R= 13/20

R= 20/13

R= 1.53

The equivalent resistance of that electrical circuit will be 1.53 ohms (approximately).
