2.9 understand that the current in a series circuit depends on the applied voltage and the number and nature of other components

The current in a series circuit is the same through out all parts of the circuit. It is worked out using the equation I= V/R. So its the total of the voltages received by the components divided by the total of all the components resistances.

      If you have a circuit with a battery of 20volts and a lamp with a resistance of 2 and a resistor with the resistance of 5:
      2+5 = 7 (the total of all the components resistances)
      20/7= 2.86
      So current is 2.86

      Hi Hannah,
      I think it's important to state the units, so 2.86A. Thank you so much for making this website, and this has helped me so much :)
