Chapter 21: Q6CQ (page 771)

Knowing that the severity of a shock depends on the magnitude of the current through your body, would you prefer to be in series or parallel with a resistance, such as the heating element of a toaster, if shocked by it? Explain.

Short Answer

Expert verified

As a result, a person would prefer to be in a series with strong resistance and a small stream flowing through him in order to avoid harm.

Step by step solution

01

Definition of the circuit.

The term "circuit" refers to a set of electrical connections.

Circuits are closed-loop or route systems that consist of a network of electrical components through which electrons can travel.

02

If you prefer to be in series or parallel, when shocked

Current is inversely proportional to resistance for a given voltage. To put it another way, the higher the resistance, the lower the current, and vice versa.

In comparison to equivalent resistance in parallel, we know that equivalent resistance in series is larger. The current must be reduced to avoid harm from shock. For a given voltage, the resistance must be greater for the current to be lesser. As a result, a person should be in series to have high resistance and a low current flowing through him.

Therefore, to avoid harm, a person would want to be in a series with strong resistance and a tiny stream flowing through him.

Some light bulbs have three power settings (not including zero), obtained from multiple filaments that are individually switched and wired in parallel. What is the minimum number of filaments needed for three power settings?

Verify the third equation in Example 21.5 by substituting the values found for the currentsl1andl3.

To measure currents in Figure \({\rm{21}}{\rm{.49}}\), you would replace a wire between two points with an ammeter. Specify the points between which you would place an ammeter to measure the following: (a) the total current; (b) the current flowing through \({{\rm{R}}_{\rm{1}}}\); (c) through \({{\rm{R}}_{\rm{2}}}\) ; (d) through \({{\rm{R}}_{\rm{3}}}\) . Note that there may be more than one answer to each part.

The \({\rm{RC}}\) time constant in heart defibrillation is crucial to limiting the time the current flows. If the capacitance in the defibrillation unit is fixed, how would you manipulate resistance in the circuit to adjust the \({\rm{RC}}\) constant \(\tau \)? Would an adjustment of the applied voltage also beaded to ensure that the current delivered has an appropriate value?

Electric fish generate current with biological cells called electro-plaques, which are physiological emf devices. The electro-plaques in the South American eel are arranged in \(140\) rows, each row stretching horizontally along the body and each containing \(5000\) electro-plaques. Each electro-plaque has an emf of \(0.15{\rm{ }}V\) and internal resistance of \(0.25{\rm{ }}\Omega \). If the water surrounding the fish has resistance of \(800{\rm{ }}\Omega \), how much current can the eel produce in water from near its head to near its tail?
