ERMM THE RESISTANCE INCREASES ) when longer
The increase in current (assuming resistance is the same and increase in voltage will lead to an increase in current) will fry your portable radio.
No, it is desirable for a battery to have a low internal resistance.
If voltage increases when current remains constant then resistance must also increase. Ohm's Law: Voltage = Current times Resistance.
The value of internal resistance of 1.5 volt battery is 0.5 ohms.
ERMM THE RESISTANCE INCREASES ) when longer
Yes, increasing temperature can cause the internal resistance of a battery to increase. This is because higher temperatures can lead to material degradation and changes in chemical reactions within the battery, which can ultimately result in higher internal resistance.
current will increase
Nothing, but the current will increase.
I don’t know
Ohm's Law states that Voltage = Resistance (Ohms) * Current (Ampere). So when you increase voltage, you increase current.
The increase in current (assuming resistance is the same and increase in voltage will lead to an increase in current) will fry your portable radio.
To increase the current you either need to reduce the resistance of the load or increase the voltage. Typically a higher wattage light bulb will decrease resistance or you could put multiple batteries in series.
No, it is desirable for a battery to have a low internal resistance.
If voltage increases when current remains constant then resistance must also increase. Ohm's Law: Voltage = Current times Resistance.
V = IR, so if you double the voltage without changing the resistance, the current will also double.
The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).
