Physics- Resistance

Question 1

In a circuit where there is a battery in series with a lamp

Answer 1

The brightness of a lamp can be used as an indication of the current flowing through the lamp.
If you connect more lamps in series, the brightness of the lamp decreases with each resistir added: current decreased with more resistors in series

Question 2

Resistor connected in series

Answer 2

Provide only one path through which an electric current can flow

Question 3

The current us a series circuit

Answer 3

Is the same anywhere

Question 4

If to connect two or more lamps in parallel

Answer 4

The brightness of the lamp increases: current increases

Question 5

Resistors connected in parallel

Answer 5

Provide more pathways for current

Question 6

Different metal conductors

Answer 6

Cause the brightness of a lamp in circuit to change. This indicates that different metals conduct electricity differently

Question 7

Current flowing through a resistor will

Answer 7

Increase the temperature of the resistor
