No. What's the total resistance in the circuit?tweety1234 said:okay so would it be like this ;
6/ 10 = 0.6 Amps

This problem asks for the voltmeter reading when the switched is closed.tweety1234 said:oh right, but i thought you don't include the internal resistance of the battery if the switch is open ?
That's the current.6/10.4 = 0.577
That's the voltage drop due to the internal resistance. But what's the full voltage reading across the battery terminals? (Does that 0.23 volts add or subtract from the battery's emf?)0577 x 0.4 = 0.23 volts
A series circuit is an electrical circuit in which the components are connected in a single loop, so that the current flows through each component in the same direction.
To calculate the total current in a series circuit, you need to use Ohm's law, which states that the current (I) is equal to the voltage (V) divided by the resistance (R), or I = V/R.
When more components are added to a series circuit, the total resistance increases, which in turn decreases the total current in the circuit. This is because the current has to flow through each component, and the added resistance makes it more difficult for the current to flow.
No, the current in a series circuit is the same at all points. This is because there is only one path for the current to flow, so it cannot split or change in value.
If the voltage is increased in a series circuit, the current will also increase, as long as the resistance stays the same. This is because Ohm's law states that the current is directly proportional to the voltage, so an increase in voltage will result in an increase in current.
