5
Q
how is total resistance of a series circuit added together
A
RT = R1+R2+R3+R4…
6
Q
how is total resistance of a parallel circuit added together
A
1/RT = 1/R1+1/R2+1/R3
7
Q
how is total current and voltage of a series circuit added together
A
current = same at all places
voltage = shared across components
