What else can I help you with?
Why the resistance high if temperature high?
for example if you check a car with a voltemeter the more the resistant the less energy it will take for example if a cars is high in temp (hot) its oil will be runny and the less time it will take to drain out.
What are the variables in a potato battery?
There are several variables involved in making a potato battery. Specifically, the variables include the potato, two pennies, galvanized nails, and some copper wire.
The rules of connecting voltmeter and ammeters in the circuit?
Connect ammeter in series and voltmeter in parallel to the circuit
How can you measure electric potential and electric current?
Potential . . .Always measured as a potential difference between two points.The most practical way to do that is with a voltemeter connectedin parallel with any circuit between the two points.Electric current . . .The most practical way to measure current is with an ammeter connectedin series in the path of the current.
