1
Q
what is a diode
A
allows current to flow in one direction only
2
Q
conventional current
A
current flowing from positive to negative
3
Q
electron flow
A
current flowing from negative to positive
4
Q
what is resistors
A
reduces the flow of current in circuit
5
Q
what is current
A
flow of electric charge
6
Q
series circuit key
A
current is same , voltage is shared , total resistance is the sum of resistance
7
Q
parallel circuit key
A
total current is shared , voltage is same , resistance is 1/R + 1/R … and then reciprocal it
8
Q
what is electrical field
A
the area around a charged object
