Question: Calculate the charging current ( (mathbf{I}_{text {Charging }}) ) of a long transmission line. 1) (frac{mathbf{V}_{mathrm{s}} tanh (gamma l)}{mathbf{Z}_{mathrm{c}}}) 2) (mathbf{Z}_{mathbf{c}} mathbf{V}_{mathbf{S}} tanh (gamma l))

Calculate the charging current ( \(\mathbf{I}_{\text {Charging }}\) ) of a long transmission line.

1) \(\frac{\mathbf{V}_{\mathrm{s}} \tanh (\gamma l)}{\mathbf{Z}_{\mathrm{c}}}\)

2) \(\mathbf{Z}_{\mathbf{c}} \mathbf{V}_{\mathbf{S}} \tanh (\gamma l)\)

3) \(\frac{\mathbf{V}_{\mathrm{s}} \operatorname{coth}(\gamma l)}{\mathbf{Z}_{\mathrm{c}}}\)

4) \(\mathbf{Z}_{\mathbf{c}} \mathbf{V}_{\mathbf{S}} \operatorname{coth}(\gamma l)\)
