Ohm’s law questions and answers pdf
Multiple Choice Questions of Electric Current and Ohm’s Law (31-45): 31.Which method can be used for absolute measurement of resistances ?
Question 3. If a piece of wire with a high resistance is connected in series with a torch bulb in a circuit what happens to the brightness of the bulb?
• Ohm’s law states that the voltage is proportional to the resistance times the current or V=IR. Power dissipated by an electrical component found by multiplying the current times the voltage or P=VI Look back at your previous work and record the voltage and current for each lamp in the spaces below. .2 sgos W) = Lamp 1 Power (W) Lamp 2 Power (W) What is the resistance p: p, O.S81Ct6W Answer
You haven’t explored the true reason why Ohm’s Law fails for certain materials. It isn’t because “resistance varies inversely to its cross-sectional area and proportionally its length” – this is the case for most wires, for example, but Ohm’s Law continues to generally apply here.

Ohm’s Law Test Questions And Answers Questions and Answers on Inductor Ohm’s law also is not applicable to the unilateral elements because they behave differently when the direction of current. test and calculators are allowed.
Questions 1 to 25: Select the best answer to each question. Note that a question and its answers may be split across a page break, so be sure that you have seen the entire question and all the answers before choosing an answer.
Question 2 (answer on your tear-sheet at the end): What is the ratio of the maximum voltage measured by the voltage sensor to the maximum current measured in the circuit when the voltage sensor is placed across your two 100-Ω resistors in parallel?
Question 17 There are two basic Ohm’s Law equations: one relating voltage, current, and resistance; and the other relating voltage, current, and power (the latter equation is sometimes known as Joule’s Law rather than Ohm’s Law): E = IR P = IE In electronics textbooks and reference books, you will ﬁnd twelve diﬀerent variations of these two equations, one solving for each variable in
The answers to this question should not create any surprises, Ohm’s Law would suggest an infinite current (current = voltage divided by zero resistance). Yet, the experiment described yields only a modest amount of current. If you think that the wire used in the experiment is not resistance-less (i.e. it does have resistance), and that this accounts for the disparity between the
