Answer:
= 27Ω
Explanation:
The voltage of a device = Resistance × Current
V=RI
Making R the subject of the formula we have R= V/I
Thus resistance = Voltage/ Current
V= 81 V
I = 3 A
Using these values in the formula for resistance we can then find the resistance of the device as follows.
R = 81 V/ 3 A
= 27Ω
The answer to your question is D!
Answer : The correct chemical equation is:
Explanation :
Balanced chemical equation : It is defined as the equation in which the atoms of individual elements present of reactant side must be equal to the product side.
According to the question, when sodium bromide reacts with lead nitrate then it reacts to give sodium nitrate and lead bromide as a products.
The balanced chemical equation will be:
The most commonly used transistor configuration is the NPN Transistor. We also learnt that the junctions of the bipolar transistor can be biased in one of three different ways – Common Base, Common Emitter and Common Collector.
In this tutorial about bipolar transistors we will look more closely at the “Common Emitter” configuration using the Bipolar NPN Transistor with an example of the construction of a NPN transistor along with the transistors current flow characteristics is given below.
