0 dBm power is transmitted, it means that actual power transmitted is :
1 mW
To solve the question regarding the transmitted power when it is expressed in decibel-milliwatts (dBm), it's essential to understand the concept of dBm and its calculation.
The term dBm refers to the power level that is expressed in decibels (dB) relative to 1 milliwatt (mW). The formula to convert dBm to milliwatts (mW) is given by:
\(P_{\text{mW}} = 10^{\left(\frac{P_{\text{dBm}}}{10}\right)}\)
Where:
- \(P_{\text{mW}}\) is the power in milliwatts.
- \(P_{\text{dBm}}\) is the power in dBm.
For the given problem, the power level is 0 dBm. Substituting this into the formula gives:
\(P_{\text{mW}} = 10^{\left(\frac{0}{10}\right)} = 10^0 = 1\) mW
Thus, 0 dBm corresponds to 1 mW of power. Hence, the correct answer is 1 mW.
Explanation of Options:
- 0 Watt: This option is incorrect as 0 dBm is not equivalent to 0 Watt.
- 1 Watt: This option is incorrect because 0 dBm does not convert to 1 Watt; it is far too large.
- 10 Watt: This is incorrect as well; 10 Watts would be a much higher power level than 0 dBm represents.
- 1 mW: This is the correct option since we calculated that 0 dBm equals 1 milliwatt (mW).
Therefore, the transmitted power equivalent to 0 dBm is 1 mW.
