Where is an ammeter placed
In series to measure current
Where is a volt meter placed
In parallel used to Measure potential difference
What is the difference between series and parallel
series - all components in one loop
Parallel - components in separate loops
What is current and the units
Rate of flow charge (amps)
What is potential difference the measure of
Energy transferred per coulomb of charge
What is resistance
Something that slows down current
The current in the diode flows in..
One direction only
The resistance of a lament lamp increase as…
the temperature of the lament increases.
The current is …potential difference across the resistor.
Directly proportional
The resistance of a thermistor decreases as
Temperature increases
The resistance of a thermistor…as light intensity increases.
Decreases
The resistance of a LDR decreases…
as light intensity increases.
How is potential difference measured
Current x resistance
