electronic tech midterm??

the battery symbol is

a voltage will influence current only if the circuit is

closed

what is the voltage for four 9V batteries connected through series-aiding?

the total voltage is 36

what happens to total resistance in a circuit with parallel resistors if one of them opens?

It increases

what happens to total current in a circuit with parallel resistors if one of them opens?

It decreases

a parallel circuit differs from a series circuit in that a parallel circuit has

more than one path for current flow

the total resistance in a parallel circuit is always less than the least resistor

true because there are more paths for the current to pass through

the largest branch resistance in a parallel circuit carries the largest branch current

false because the current is greatest where the resistance is least

if the resistance total in a series circuit doubles, current will:

be halve

the total resistance of a series circuit always depends on the highest value resistor in that circuit

false because the total resistance of a series circuit is equal to the sum of all individual resistances

if doubling the voltage across a resistor doubles the current through the resistor then

the resistor value increased

if the resistance in a circuit with constant voltage increases, the current will

decrease

doubling the voltage across a resistor will cut the current by half

false because v² / r = a

Ohm's law equation

V=IR
