What is the net resistance of the circuit connected to the battery in the figure?

To find the net resistance of the circuit connected to the battery in the figure, you need to calculate the total resistance by adding up the individual resistances in the circuit.


How do you Calculate the voltage of a battery if the resistance is 20hms and the current is 0.35 amperes?

Use Ohm's law. V = I * R where V is voltage in volts, I is current in amperes, and R is resistance in ohms.


How do you calculate ah of battery?

You could put a know resistive load on the battery and then monitor the voltage across the load until the battery was at zero volts. Using Ohm's Law you can calculate the current at any time. Current = Voltage / Resistance. You can multiply the average current times the number of hours for the battery to go to zero.


Is it desirable for a battery to have a high internal resistance?

No, it is desirable for a battery to have a low internal resistance.


Calculate the voltage of a battery if the resistance is 80 ohms and the current is 0.5 amp?

Ohm's law: Voltage is resistance times current. 80 ohms time 0.5 amperes = 40 volts.


If you have a circuit consisting of a battery and a wire What two factors determine the amount of current in the circuit?

The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).


What information does the battery internal resistance chart provide?

The battery internal resistance chart provides data on how much resistance the battery has to the flow of electricity within it. This information can help determine the battery's efficiency and performance.


Actual internal resistance of 1.5 volt battery?

The value of internal resistance of 1.5 volt battery is 0.5 ohms.


How many amps will you get on a 9 volt battery with a 100 ohm resistor and a 100 ohm resistor and a 470 ohm resistor?

You need to calculate the equivalent resistance. For instance, if the three resistors are connected in series, simply add all the resistance values up. Then, you calculate the current (in amperes) using Ohm's Law (V=IR); that is, you need to divide the voltage by the resistance.


What is meant by the internal resistance of a battery?

There is internal resistance in a battery because a battery is not an ideal voltage source. It may be close, but it is not ideal. As a result, analytically, there will be some series resistance, resistance which places a limit on the maximum current that the battery can provide. While no battery is ideal, most are sufficiently ideal to not require any consideration of the internal resistance. If your circuit is dependent on the internal resistance of a battery, then it is probably not well suited for that application.


How do you calculate contact resistance?

Resistance is resistance , no matter if it is contact resistance or any other resistance. And formula is R = V / I.


How do you calculate resistance box for slip ring motor?

To calculate the resistance for a slip ring motor, there is an equation that must be solved. This is Torque = S/R. S is the slip of the motor and R is the resistance of the motor.
