When a volt meter is placed in a circuit on its own the reading is say 4v. But when a component, 'x', is placed in parallel the voltage drops. Why is this??

Voltage drop in circuits with parallel components refers to the decrease in voltage that occurs across each individual component in a parallel circuit. This is due to the fact that the total current in a parallel circuit is divided among the different branches, resulting in a decrease in voltage across each branch.
To calculate voltage drop in a parallel circuit, you can use Ohm's Law (V = IR) for each individual component. First, calculate the total current in the circuit by summing up the individual branch currents. Then, use Ohm's Law to find the voltage drop across each component by multiplying its resistance by the current flowing through it.
Voltage drop in parallel circuits is caused by the distribution of current among the different branches. As current flows through each branch, it encounters resistance, which leads to a decrease in voltage across that branch. This results in a decrease in voltage across each component in the circuit.
Voltage drop can have a significant impact on the performance of a circuit. It can cause a decrease in the overall voltage and power delivered to the components, which can result in reduced efficiency and performance. It can also cause overheating and potential damage to components if the voltage drop is too high.
One way to minimize voltage drop in parallel circuits is to use components with lower resistance values. This will reduce the overall resistance in the circuit, resulting in a smaller voltage drop. Additionally, proper circuit design and wiring techniques can also help to minimize voltage drop.
