Consider an electromagnet (e. g. in a relay) that is operated at 50 a. if the inductance of the coil is 100 h and the time to switch-off the current is 1 ms, what voltage will be developed across its terminals?

5 x 10⁶ volts

Explanation:

= Initial value of current = 50 A

= Final value of current = 0 A

Δt = time taken = 1 ms = 0.001 s

 = Voltage developed across the terminals

Voltage developed across the terminals is given as

 = 5 x 10⁶ volts

this means that the temperature of both substances will be equal

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
