Flashcards in P2.2 Controlling And Using Electric Currents Deck (12):

1

## What do we use to measure voltage?

### A voltmeter

2

##
What happens to current in a parallel circuit?

What happens to voltage?

### Current remains the same and voltage is split

3

## What is another name for voltage?

###
Potential difference

4

## What is resistance measured in?

### Ohms

5

## What is the equation for resistance?

### Potential difference/current

6

## What is a thermistor?

### A heat dependent resistor

7

## What is a LDR

### A light dependent resistor

8

## What is a diode?

### A resistor that only allows current to flow one way, so A.C does not work

9

## Do the resistances of LDRs and thermistors go up or down as the factor increases.

### The resistance decreases as the factor increases

10

## What is the equation for power?

### Current*potential difference

11

## What do we use to measure current?

### An ammeter
