A student wants to reduce energy wasted as heat in transmission lines. Which approach is most effective?
What is the unit of electrical resistance?
Which effect will increasing temperature usually have on the resistance of a metal conductor?
Two resistors, 4 O and 6 O, are connected in parallel. What is the total resistance?
Which statement about resistors in series is correct?
Which material change will decrease a wire’s resistance at constant length and temperature?
A student uses a voltmeter and ammeter to find the resistance of a resistor by measuring V and I. Which method gives the most accurate resistance?
A wire’s resistance depends on its length. If the length of a uniform wire is doubled while keeping other factors constant, what happens to its resistance?
A 24 V supply drives a current of 3 A through a resistor. How much energy is delivered to the resistor in 10 s?
