Question 28
Easy

An engineer investigates how connecting identical micro-heating elements in parallel affects the total current drawn from a constant voltage source.

They measure the total current from a 5.00 V power supply as they vary the number of parallel elements.

Table 1 shows their results.

493.65.00
370.25.00
246.85.00
123.45.00

Using the data in Table 1, predict the current from the power supply when there are 5 micro-heating elements connected in parallel.
