The current in a circuit, expressed in milliamperes, is
1,000 x (battery or power supply voltage)/(resistance connected between the power supply terminals)
If you increase the voltage of the battery or power supply, the current in the circuit
increases proportionally, at least until something in the circuit gets hot, melts, fuses,
and opens the circuit.
To increase voltage output when using more then one battery connect the batteries in series.
It should decrease
You would have to apply a higher voltage from outside - for example, in the case of DC, connect a battery that provides more voltage, or connect more than one battery in series; or in the case of AC, use a transformer to increase the voltage.
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.
A megger measures very high resistance to check insulation, therefore it must use very high voltages so as to detect the very small current flowing.
To increase voltage output when using more then one battery connect the batteries in series.
The power in the circuit will increase.
It should decrease
Ohm's Law states that Voltage = Resistance (Ohms) * Current (Ampere). So when you increase voltage, you increase current.
When the alternator starts charging the battery voltage will increase about two volts to charge the battery.
To increase voltage, you can connect batteries in series. This involves connecting the positive terminal of one battery to the negative terminal of another battery. The total voltage will be the sum of the individual battery voltages. Make sure the batteries are of the same type and capacity for best results.
If the 2nd battery is connected "in series" with the 1st battery, the voltage will increase & the motor will run faster. If the 2nd battery is connected "in parallel" with the 1st battery, the voltage will not change, but the total battery capacity will be greater & therefore battery life will be longer than when using just 1 battery.
Battery fails to charge, alt light comes on, sometimes only at low revs. Check with meter shows low or no charging voltage (close to or less than battery voltage) voltage does not increase to charging volts with engine revs increase
You would have to apply a higher voltage from outside - for example, in the case of DC, connect a battery that provides more voltage, or connect more than one battery in series; or in the case of AC, use a transformer to increase the voltage.
To increase the total voltage output, connect the 3 batteries in series by connecting the positive terminal of one battery to the negative terminal of the next battery, and so on. This will result in a total output voltage of 4.5 volts.
When a battery is added to a parallel circuit, the total voltage in the circuit increases as the new battery adds its voltage to the existing voltage sources. The total current in the circuit may also increase as the additional voltage motivates the charges to flow through the parallel branches of the circuit.
Yes.If you connect the batteries in series the total voltage will be the sum of the voltages of the batteries.For example if you connect a 12 volt battery in series with a 6 volt battery the total voltage will be 18 volts.
