If a electrician measures the current of a circuit to be 100 Amps and the circuit is only designed to have a current of 80 Amps,
Talja [164]

There are too many batteries in the circuit, which increased the emf of the circuit and in turn increased the current in the circuit.

<h3>Current in the circuit</h3>

The current in the circuit is determined by applying Ohms law as shown below;

V = IR

where;

  • I is the current
  • V is the voltage
  • R is the resistance

I = V/R

At a constant resistance of the circuit, the current in a circuit will increase when the emf of the circuit increases.

Thus, we can conclude that, there are too many batteries in the circuit, which increased the emf of the circuit and in turn increased the current in the circuit.

s2008m [1.1K]

Answer:

The correct answer is the number 4. A wave on a pond is a mechanical wave which requires a medium to travel.

Explanation:

Mechanical waves are those that need a material medium to propagate. The waves of the sea and the waves that we produce on a guitar string, the sound, are examples of mechanical waves. Electromagnetic waves are energetic pulses capable of propagating in a vacuum. This way, a wave on a pond is a mechanical wave which requires a medium to travel.
