The potential difference across the 3 ohm
WebbThis gives one of the methods, called Ohm's law, of determining the potential difference across a resistor. Ohm's law says {eq}V = IR {/eq}. Another method to determine the … WebbJokes apart! The basic equation for this is V = I*R, where V is voltage aka potential difference across, I is current flowing through and R is the resistance value. So, basically …
The potential difference across the 3 ohm
Did you know?
WebbIdeally the resistance is so much larger that the potential difference across the wires is tiny. You can do this by making the wires as thick as you can afford, and from a good … WebbThree 5 ohms resistors connected in parallel have a potential difference of 60v. applied across the combination. The current in each resistor is A. 4A B. 36A C. 12A D. 24A E. 10A Correct Answer: Option C Explanation since they are in parallel, the same voltage across = I …

Consider the circuit shown in the figure.a) Find the current in the 38.0 ohm resistor.
Webb16 jan. 2024 · Ans: Ohm’s law states that the current flowing through a conducting wire is directly proportional to the potential difference across its two ends, provided the temperature remains constant. Q.3: Define the resistance of a conductor. Webb21 aug. 2024 · Question 3. Name a device that helps to maintain a potential difference across a conductor. (CBSE 2014) Answer: Cell or battery. Question 4. Write S.I. unit of resistivity. (CBSE 2015) Answer: Ohm-metre (Ωm). Electricity Class 10 Important Questions Short Answer Type. Question 1.
WebbAs the resistors 9 Ω and 6Ω are connected in parallel, therefore potential difference across them is the same. ∴ 9 I 1 = 6 I 2 ; I 2 = (9 × 2)/6 = 3A. current drawn from the battery is. I = I 1 + I 2 = (2 +3) A = 5A. The potential difference across the 2 Ω resistor is = (5 A) (2 Ω ) = 10 V. Hence option 4 is correct.
