| C:/Users/tylrg/Downloads/Hw-7-Electric-circuits-II.pdf The diagram below shows a small water heater that uses electrical energy to heat water. The heating element is a small resistor labeled R1oad = 5.0 N immersed in the water. A 20 V ideal emf device supplies current and there is an adjustable resistor Ra in series. The value of the adjustable resistance can be changed to be anywhere between 1.0 - 3.0 N. The adjustable resistor is initially set to 2.0 Q and the switch is closed. (a) What is the voltage drop across the heating element? (b) How much energy is supplied by the source if the water heater runs for 10 minutes? (c) What fraction of this energy is actually used to heat the water? Please express your answer as a percentage, using only two significant figures. (d) Suppose the heating element degrades and corrodes and its resistivity slowly increases as the equip- ment becomes older. • Does the voltage drop across the heating element increase, decrease or remain the same as the…
A 120-W lightbulb connected to a 120-V source experiences a voltage surge that produces 138 V for a moment. By what percentage does its power output increase? Assume its resistance does not change. %
I need help on problem 33)Consider the resistor described in problem 1 carrying a current of 1 mA. If the voltage drop across the resistor is 25:0 Volts, what is the resistance (in k )? (b) Electrical currents crossing the human body in excess of 0.3A are typically deadly. If electrical current has a direct pathway to the heart, it can interfere with your heart beat. In such a case, it only takes about 1 mA to be deadly. Fortunately, under dry conditions, the hand-to-hand resistance of the human body can be as large as 100,000 : This is primarily due to the resistance of your skin. Unfortunately, if your skin is wet or chapped, your resistance can be as low as 1000 . If you touch a 9 Volt transistor radio battery, placing one hand on the positive electrode, and the other hand on the negative electrode, what will be the current passing through your body with dry skin? With wet skin?

60 W 30 W Bulb A Bulb B V,-120V Vs-120V PA-60W Pa-30w Light bulb A has a power rating of 60 W when plugged into a 120 v outlet. Bulb B has a power rating of 30W when plugged into the same 120V outlet. Which of the following are correct statements? SELECT TWO ANSWERS a. Bulb A has twice the resistance of bulb B b. The following equation relates the current through each bulb la = 218 c. If both bulbs were turned on for 5 minutes bulb B would use twice the energy of bulb A O d. Bulb A has half the resistance of bulb B
