An ideal (100% efficient) step-up transformer has a primary voltage VpV_{\text{p}}Vp and a primary current IpI_{\text{p}}Ip. Which option correctly compares the secondary voltage VsV_{\text{s}}Vs with VpV_{\text{p}}Vp and the secondary current IsI_{\text{s}}Is with IpI_{\text{p}}Ip?
Secondary voltage is greater than VpV_{\text{p}}Vp and secondary current is greater than IpI_{\text{p}}Ip
Secondary voltage is greater than VpV_{\text{p}}Vp and secondary current is less than IpI_{\text{p}}Ip
Secondary voltage is less than VpV_{\text{p}}Vp and secondary current is greater than IpI_{\text{p}}Ip
Secondary voltage is less than VpV_{\text{p}}Vp and secondary current is less than IpI_{\text{p}}Ip
