What will happen to an electrical coil when the direct current flowing through the coil is increasing?

🔍 Key Concepts

• Electromagnetic induction in a coil when current changes • How flux and current are related in a simple inductor (coil) • The idea of a self-induced voltage (back EMF) when current is changing

💭 Think About

• If the current in a coil is increasing, what happens to the magnetic field (flux) around that coil? • According to the idea of self-induction, does a changing current in a coil help the change or oppose the change? • Which choice describes something that directly opposes the applied voltage rather than helping it?

✅ Before You Answer

• Recall that in a simple coil, flux is proportional to current (more current → more flux). Eliminate any option that contradicts this. • Think about whether an increasing current would normally increase or decrease power in a resistive circuit. • Identify the choice that mentions a voltage that resists the change in current, which is a key feature of inductors.

Question 1 of 27070

What will happen to an electrical coil when the direct current flowing through the coil is increasing?

the increasing current reduces the amount of flux produced

the increasing current changes the coil's impedance

the increasing current reduces the power consumed

the increasing current produces a voltage in opposition to the applied voltage
