If anyone knows how to do these, . i only need one answer from each of the two problems.

Step-by-step explanation:

95) We know, thanks to Ohm's law that:

Where:

V= voltage

I = electric current

R = resistance or impedance.

We also know that there are two types of electric circuits: the resistances can be connected parallel to each other, or a series circuit, where the electricity has only one path to flow. In this case, the total resistence or impedance can be calculated adding each impedance.

a) R= R1 + R2 + R3 = 2 Ω + 5 Ω + 7 Ω = 14 Ω

b) R = 12 Ω+ 8 Ω +15 Ω = 35 Ω

c) R = 2 Ω +8 Ω +6 Ω +4 Ω= 20 Ω

96)

a)

Ω

b)

Ω

c)

Ω

i dony know

step-by-step explanation:

one set of data has more variation than the other. hope this !
