Open Question: What is the current of the 25ohms resistor?
Bozhena Member since:April 21, 2011Total points:95 (Level 1)Three resistors, of 40 ohms, 60 ohms, and 120 ohms, are connected in parallel, and this parallel group is connected in series with 15 ohms in series with 25 ohms. The whole system is then connected to a 120-V source. Determine (a) the current in the 25 ohms, (b) the potential drop across the parallel group, (c) the potential drop across the 25 ohms, (d) the current in the 60 ohms, (e) the current in the 40 ohms.Answer QuestionBe the first to answer this question.
Open Question: How to find induced current?
WeArePen... Member since:September 18, 2008Total points:246 (Level 1)An 17-turn coil has square loops measuring 0.181 m along a side and a resistance of 5.39 ?. It is placed in a magnetic field that makes an angle of 43.5° with the plane of each loop. The magnitude of this field varies with time according to B = 1.89t3, where t is measured in seconds and B in teslas. What is the induced current in the coil at t = 3.61 s?Answer QuestionBe the first to answer this question.
Open Question: what is the current? try to answer this question if you can?
The SI unit for measuring the rate of flow of electric charge is the ampere, which is charge flowing through some surface at the rate of one coulomb per second. Electric current is measured using an ammeter
Mathematically it can be written as
Q = i * t ; where Q = charge in Coulomb, i = current in amp., and t = time in sec
so in your question Q = 10, 800 C, t = 1 hour = 60x60 = 3,600 sec
so 10,800 = i * 3,600 ; or
i = 10,800 / 3,600 = 3 amp. ---------- Answer
Hope this helped.

Open Question: A lightning bolt strikes one end of a steel lightning rod, producing a 15,000-A current burst that lasts for 6?
Open Question: What is Static electricity and Current electricity ?
"static electricity" or electrostatics is studying charge situations whereby all systems are in ELECTROSTATIC EQUILIBRIUM. That is, they aren't really actively doing any re-distribution.
"Current electricity" is what you shouldn't call it. You should just call it circuits. That is when we focus a study on an application of when electrostatic equilibrium ISN'T the case, and the results are interesting to us.
