The heart cells must contract simultaneously to move blood.
This means that it needs to act fast and efficiently.
Therefore, the connections among heart cells are characterized by :
- having many branches
- having many communicating junctions
The correct option should be <u>A</u>
<u>Answer</u>:
Step Down Transformer: The Transformer that expands the voltage from Primary (essential) to Secondary (auxiliary) (more optional twisting turns than essential winding turns) loops called Step Down Transformer.
<u>Explanation</u>:
A transformer that reduces high voltage to low voltage is called a step-down transformer. The step-down transformers are that transformers which have high turns on its primary coils than secondary.
Where
Vp = Voltage in Primary Coil
Ip = Current in Primary Coil
Vs = Voltage in Secondary Coil
Is = Current in Secondary Coil
