To design a practical current source, the resistance should be connected in______________and its value should be______________Ω

Two resistors of resistance 4 Ω and 6 Ω are connected in parallel to a cell to draw current 0.5 A from the cell.(a) Draw a labelled diagram of the arrangement.(b) Calculate the current in each resistor.

For the circuit shown in fig. Find the current flowing through the 10 Ω resistor.

Karl measures the current through a resistor. What else will he need to measure in order to work out its resistance? Give the full name, not the symbol.

Name the type of component that has a greater resistance as the current through it increases.

An electrician measures the current flowing through a 1000 Ω resistor as 0.02 A. Calculate what the voltage supplied to this resistor must be.
